FAQ

Why do some MTB frames use an 83mm shell instead of 73mm?: The 83mm shell is specific to downhill and heavy-duty freeride frames that use a wider shell for improved tire clearance and frame geometry. It is not interchangeable with standard 68mm or 73mm shells.

How do I know if my frame needs the 83mm version?: Confirm your frame's exact shell width (measured between the inside faces of the shell) and that your crankset is a SRAM DUB model designed for the 83mm shell before ordering.

What tools are needed to install this bottom bracket?: A standard spanner-type BSA bottom bracket tool is required. Install using the same drive-side counterclockwise/non-drive clockwise convention as any English/BSA bottom bracket.

Best For

Downhill and freeride mountain bikers on frames with 83mm English/BSA threaded shells running SRAM DUB cranksets who need the correct wider-shell bottom bracket.
